I've said it before, but if your baby rejects a food don't be afraid to keep retrying it down the road. For example, a few months ago Buttercup didn't care for raw mushrooms. But, the other night I was cooking dinner and a sliced mushroom landed on the floor near where Buttercup was playing. It promptly went into her mouth. And, she "asked" for more of it!
So, there you have it: a previously rejected food is now a yummy treat.
